Abstract
A video coder may determine contexts for entropy coding bins of a last significant coefficient position syntax element. For example, a video coder may determine a respective context for each of one or more bins of a syntax element indicating the position of the last significant coefficient in a transform block using a function of a size of the transform block, wherein the function outputs the respective context such that the same context is not used for transform blocks of differing sizes.
